Research on RS(255,223) code in concatenated decoder system

RS(255,223) code is used in concatenated code system for its strong error-correcting ability for burst error. The most important problem of the design of RS decoder is the key equation solution (KES). In this paper, BM iterative decoding algorithms for KES is introduced, and its implementation structure is also described. Simulation shows that the designed RS(255,223) has suffi ciently met the requirement of throughput in the concatenated decoder.
